Definitions

  • This invention relates generally to electrical connectors and pertains more particularly to connectors having both signal and power contact members therein.
  • electrical connectors need only conduct therethrough relatively low level, i.e., low voltage, signals. Given such signal levels, the sealing relationship between the connector housing and the contact members carrying the signals is not critical.
  • the power contact member is typically required to be of blade shape interiorly of the connector housing.
  • One known practice for obtaining a high degree of sealing relationship between the power contact member and the connector housing is to mold the housing about the contact members, including the fully blade-shaped power contact member. This practice is relatively costly and complicated as compared to the practice of press-fitting contact members into a pre-existing housing.
  • Difficulty attends press-fitting of a blade-shaped contact member into a housing and obtaining a high degree of sealing relationship between the contact member and the housing.
  • edge warpage attends press-fitting, as does non-uniform hoop stress.
  • US-A-3670294 discloses an electrical connector comprising a body and passages extending through the body, there being electrical contact members resident in the passages, the passages being circular in configuration at one end and rectangular at the other, and each contact member having a portion being circular in configuration resident in the circular part of the associated passage, but without contact therewith, and a portion of blade-shaped configuration extending through the rectangular portion of the passage, the contact pins each having a retention portion with elements to engage the body material in the region of the rectangular part of the passage.
  • the arrangement involves no sealing between the contacts and the body.
  • the present invention has as its primary object the provision of a connector having a press-fit power contact member meeting the requirements of a sealed relation between the contact member and the connector housing and of presenting a blade-shaped contact portion interiorly of the connector housing.
  • an electrical connector comprising a housing of electrically insulative material defining an interior compartment and passages extending from said interior compartment to an exterior surface of said housing, and electrical contact members resident in said housing passages, at least one of said passages being circular in configuration, the contact member resident in said one passage having a portion being circular in configuration and in press-fit sealed relation with said housing, said contact member resident in said one passage having a further portion resident in said interior compartment of blade-shaped configuration.
  • the invention further provides a method of making a connector having a power contact in sealed relation therein, comprising the steps of:
  • Fig. 1 is a perspective view of a connector in accordance with the invention.
  • Fig. 2 is a perspective view of the Fig. 1 connector as would be seen from viewing its undersurface.
  • Fig. 3 is a perspective view of the power contact member of the connector of Figs. 1 and 2.
  • Fig. 4 is a front elevation of the power contact member of the connector of Figs. 1 and 2.
  • Fig. 5 is a plan view of Fig. 4
  • Fig. 6 is a left side elevation of Fig. 4.
  • Fig. 7 is a right side elevation of Fig. 4.
  • connector 10 has a housing 12 comprised of electrically insulative material. Housing 12 is preformed to define interior compartments 14 and 16 and passages for receipt of press-fit contact members, inclusive of two groups of contact members 18 and 20, and press-fit power contact member 22. All contact members define exterior contact portions, shown in Fig. 2 as accessible at the connector undersurface and contact portions (not shown) in compartments 14 and 16 for mating engagement with contact portions of contact members of a mating connector (not shown). As is seen also in Fig. 2, mounting post 24, formed integrally with housing 12, extends below the connector undersurface and is adapted to seat in a recess of a printed circuit board which has plated through holes (not shown) for receipt of contact members 18, 20 and 22.
  • power contact member 22 has two dissimilarly configured portions, portion 22a being cylindrical and portion 22b being blade-shaped.
  • the housing passage 12a (Fig. 2) for residence of power contact member 22 is circular and of diameter somewhat less than the diameter of portion 22a, whereby upon press-fitting of power contact member portion 22a into passage 12a from the interior of compartment 16, a round pin, round hole situation is at hand, giving rise to fully uniform hoop stress and a water-tight relation between contact member 22 and housing 12.
